that's not a problem.
bpf backend produces code that runs in the kernel.
That's no different than x86 backend produces code that runs in the kernel.
bpf isa is free.
There is iovisor/bcc project that uses both clang rewriter and
llvm bpf backend statically linked, but it's using apache2 license,
so no problem either.
